How does the brain perceive temperature
WebThe middle layer of the skin, or dermis, stores most of the body's water. When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range. WebThe hypothalamus, with regard to temperature, can quite accurately be compared to a thermostat. It is responsible for maintaining the body temperature within a tight range, usually around 37°C [98.6 °F]. This is the temperature that is most optimal for the body to conduct its metabolic processes efficiently.
